various loops which you have outlined.

Inasmuch as the bush planes do not operate on a nautical mile
basis, but on a rate of so much per hour, and since the speed
of these planes is figured in land miles instead of nautical
miles, the total time required to make the amount of flights
you have indicated, would be between 150 and 200 hours.
Obviously this is impossible. Such a program would require

the caching of gasoline at each one of the more distant stations
prior to the commencement of the actual summer's work, for the
Norseman does not carry sufficient gas to make the round trip
from Point Barrow to any one of your more distant stations

with a full pay load. The caching of this of course would have
to be paid for at the same rate that the later flights cost,
and the ambitious program you have outlined would take more
time and money than is available to carry on the bush plane
flying program for the entire group of scientists to be
stationed at Point Barrow during the summer of 1951.

As you undoubtedly know, Dr. Setzer of the National Museum will
also be working in the field during this summer, and it had
been a part of my general planning for the two of you to

more or less divide the area between you, so that neither would
be required to do as much moving from one spot to another as

is indicated in your proposed schedule. It may be possible

to get-each of you to the various parts of the Reserve without
exactly duplicating the camps from which you would operate,

and do so with less expensive flying programs than you have
outlined,

As indicated in my April 2lst letter, the chances are better
than three to one that you will be unable to do bush flying

as early as June 10th. The period between June Ist and July lst
is normally considered the breakup time, when almost no bush
flying is feasible. It is possible that if you arrive by

June 10th that arrangements can be made for you to spend a
couple of weeks in the vicinity of Umiat, at approximately

69 deg. 28 min. N and 152 deg. W. There is a Contractors!

camp at this point and if you desire to do so, it is possible
that you might work up or down the Colville Kiver a distance

of from 50 to 100 miles by using a skiff and an outboard motor.
In that way, you could determine the length of your stay at
any one point at your own convenience. It is probable that a
team of paleontologists will need to be operating in the Umiat
area during the same period, and your team and theirs will
undoubtedly have to arrange for cooperative alternating use

of the skiff and outboard motor, if you wish to work more than
a few miles from the Umiat camp.
